(54) Telephone Call Processing


(57) This invention relates to methods and apparatus for the delivery of enhanced telephony services for calls received on local telephone exchange switches. The invention employs an intercept node which intercepts number portability query messages and ascertains whether enhanced telephony services should be applied to a call with reference to an enhanced telephony service user database. If enhanced telephony services are to be applied to the call, the call is routed to a node capable of applying enhanced telephony services, otherwise the call is forwarded on to a number portability processing node. Enhanced telephony services may thus be provided in relation to calls received at local telephone exchange switches which do not themselves support identification of enhanced telephony service users and associated triggering to initiate the provision of enhanced telephony services, but which do generally support a number portability mechanism.
